Abstract:The beamforming technique has been successfully used for real-time ultrasound imaging and applications. Traditionally, the most commercially available ultrasound systems still implement standard Delay-and-Sum (DAS) beamforming for Bmode imaging. This technique performs the time delay and coherent summation of ultrasonic radiofrequency (RF) echoes received by individual transducer elements to align the backscattered signals at the focal point. However, the transducer aperture size and system operating frequency… Show more
